I'm trying to filter by date and this shows up in my posts box:

Fatal error: Uncaught Error: Call to undefined function mysql_real_escape_string() in /home/samoorelex/public_html/svlexington.net/wp-content/plugins/anthologize/includes/class-project-organizer.php:469 Stack trace: #0 /home/samoorelex/public_html/svlexington.net/wp-content/plugins/anthologize/includes/class-project-organizer.php(106): Anthologize_Project_Organizer->get_sidebar_posts() #1 /home/samoorelex/public_html/svlexington.net/wp-content/plugins/anthologize/includes/class-admin-main.php(339): Anthologize_Project_Organizer->display() #2 /home/samoorelex/public_html/svlexington.net/wp-content/plugins/anthologize/includes/class-admin-main.php(485): Anthologize_Admin_Main->load_project_organizer('3927') #3 /home/samoorelex/public_html/svlexington.net/wp-includes/class-wp-hook.php(286): Anthologize_Admin_Main->display('') #4 /home/samoorelex/public_html/svlexington.net/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters('', Array) #5 /home/samoorelex/public_html/svlexington.net/wp-includes/plugin.php(453): WP_Hook in /home/samoorelex/public_html/svlexington.net/wp-content/plugins/anthologize/includes/class-project-organizer.php on line 469

Any help?

Thanks,
